9.2 Input of the Medium Parameters
It is possible to specify which media will be displayed in the scroll list (see section 13.5).
For the programmed parameters of common media see annex C.3.
If a medium is selected from the scroll list, the menu item for the input of the medium temperature is displayed directly (see
section 9.2.4).
If Other Medium is selected, the medium parameters have to be entered first:
• average sound speed of the medium
• range around the average sound speed of the medium
• kinematic viscosity
• density
9.2.1 Sound Speed
The sound speed of the medium is used for the calculation of the transducer distance at the beginning of the measure-
ment. However, the sound speed does affect the measuring result directly. Often, the exact value of the sound speed for a
medium is unknown. Therefore, a range of possible values for the sound speed has to be entered.
9.2.2 Kinematic Viscosity
The kinematic viscosity has an effect on the flow profile of the medium. The entered value and other parameters are used
for the profile correction.
9.2.3 Density
The density is used to calculate the mass flow (product of the volumetric flow rate and the density).
Select the medium from the scroll list.
If the medium is not in the scroll list, select Other Medium. Press ENTER.
Enter the average sound speed of the medium. Press ENTER.
This display will only be indicated if Other Medium is selected.
Select auto or user. Press ENTER.
auto: The area around the average sound speed is defined by the transmitter.
user: The area around the average sound speed has to be entered.
Enter the area around the average sound speed of the medium. Press ENTER.
This display will only be indicated if user is selected.
Enter the kinematic viscosity of the medium. Press ENTER.
This display will only be indicated if Other Medium is selected.
Note! If the mass flow is not measured, press ENTER. The other measuring results will not be affected.
Enter the operating density of the medium. Press ENTER.
This display will only be indicated if Other Medium is selected.
